ESPN.com'sDarren Rovellreported Kaepernick had remained with Nike since the company signed him to an endorsement deal in 2011 and will feature in Nike's 30th anniversary celebration of its "Just Do It" campaign.

Gino Fisanotti, Nike's vice president of brand for North America, explained to Rovell how Kaepernick's social advocacy helped Nike identify him as a prime candidate for the campaign.

"We believe Colin is one of the most inspirational athletes of this generation, who has leveraged the power of sport to help move the world forward," Fisanotti said. "We wanted to energize its meaning and introduce 'Just Do It' to a new generation of athletes."

According to Yahoo Sports'Charles Robinson, Kaepernick's Nike deal is structured similarly to that of a typical star-level player in the NFL. He'll have his own apparel line with Nike and receive "millions per year plus royalties."

While Rovellrefuted Robinson's report about Kaepernick getting a signature Nike merchandise line, Robinsonresponded that his sources said "there is absolutely a contract commitment by @nike for a signature shoe and 'Kaepernick 7' line of apparel."
